President Obama flubbed the name of Buffalo, N.Y.’s mayor while speaking at the city’s state-university campus, confusing the mayor, Byron Brown, with the city’s congressman, Democrat Brian Higgins. When the president paused for applause after praising the mayor, the audience shouted out the correct name, and he corrected himself.

“This is what happens when you get to be 52 years old,” Obama said. “When I was 51, everything was smooth.”
